Abstract
Heating equipment for supplying steam and heated gas, including a combustion chamber from which come flue gases which flow through an enclosure, heating on the way at least one bundle of tubes in which water flows and gives off steam, and which further includes at least one bundle of tubes traversed by a gas and located in the enclosure so as to be heated by the flue gases from the combustion chamber.
Claims11
Heating apparatus for use with an installation using steam and hot gas and including a combustion chamber (22) out of which waste gases pass which circulate within an enclosure (21) and during their passage provide heating of a bundle of vaporizer tubes (41, 42, 45), which supply water vapor to a bundle of super-heating tubes (51, 52) which provide super-heated steam and a bundle of tubes (71) in which a gas furnished by an exterior source of gas circulates, said vaporizer tubes (45) being located upstream of said bundle of tubes (71), said apparatus comprising a partition (24) which divides said enclosure into two chambers so as to separate two flows of waste gases, one of said chambers containing said bundle of tubes (71) in which said gas circulates and the other of said chambers containing at least one bundle (51, 52) of super-heating tubes which are supplied with dry steam damper means (81, 82) being provided on each side of said partition for controlling the flow of the waste gases through each of said chambers.
